Foremost is that the CrazyROM can be implemented in one chip (i.e PAL, GAL, CPLD) or even a small 64-byte PROM as others here have suggested.


The catch-22 is that if you're going to depend on programming one of those devices for the bootstrap to work, you might as well go ahead and program an ISP microcontroller and be done with it. :)

               if you, just for once, would take the time to read            01/01/70 00:00      
                  So ... where's the help for him in that example?            01/01/70 00:00

                  You're right about that ...            01/01/70 00:00      
                     BINGO!            01/01/70 00:00      
                        So why not use a PROM?            01/01/70 00:00

      .            01/01/70 00:00      
         Yes, but, still, why dismiss ROM?            01/01/70 00:00      
   Sooooooooooooooooooooooooooooooooooooo complicated            01/01/70 00:00      
      That's an understatement ...            01/01/70 00:00
